Description

Technical Field

[0001] The invention relates to the technical field of guide rail processing, and in particular to an elevator guide rail precision leveling machine. Background Art

[0002] Elevators play an important role in daily life and are an indispensable means of transportation in high-rise buildings, commercial centers, residential areas and public facilities. When elevators are produced and installed, a guide system needs to be added to limit the freedom of movement of the car and counterweight to ensure that the car and counterweight run smoothly without swaying. The core component responsible for limiting the movement of the car in the elevator guide system is the elevator guide rail, which is installed on the side wall of the elevator shaft and is required not to bend due to processing during the production process. Therefore, the elevator guide rail needs to undergo two rounds of correction during the production process to correct its bending and twisting, which are the initial correction during rough processing and the fine correction during fine processing.

[0003] Existing precision straightening machines generally choose roller straightening machines or three-point simply supported straightening machines. The former is highly efficient, but the adjustment range of the downward pressure is small and difficult. Although the latter has high precision, it is more suitable for shaft parts with circular cross-sections. The cross-section of elevator guide rails is mostly T-shaped, which is not conducive to the three-point simply supported straightening machine to find the inflection point. Therefore, a machine is needed that can achieve the straightening accuracy of the three-point simply supported straightening machine and can find the inflection point of the T-shaped cross-section guide rail.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0029] Reference Figure 1~Figure 2 , which is a first embodiment of the present invention, provides an elevator guide rail precision straightening machine, comprising:

[0030] A base 100, a panel 200 is fixedly disposed on the top of the base 100, a pair of panels 200 are disposed and divide the top of the base 100 into three parts, and,

[0031] A placement assembly 300 is used to place and fix the T-shaped guide rail on the top of the base 100, which includes a pre-treatment member 301 disposed on the top of the base 100 and a clamping member 302 disposed on one side of the enclosure 200;

[0032] The straightening assembly 400 is used to find and straighten the inflection point of the T-shaped guide rail, and includes a measuring member 401 arranged on one side of the base 100, a pull rope member 402 arranged on one side of the measuring member 401, and a correcting member 403 arranged on one side of the enclosure 200.

[0033] At the top of the base 100, two panels 200 are arranged in parallel and spaced a certain distance apart and symmetrically arranged in parallel about the center line of the top of the base 100, so that the base 100 can be divided into three parallel areas, wherein the middle area is larger and is used to place the T-shaped rail that needs to be finely corrected. When in use, the placement component 300 is first used to fix the T-shaped rail as a whole at the center position of the top of the base 100, and then the straightening component 400 is used to find the inflection point of the T-shaped rail, and then the inflection point is straightened. Example 2

[0034] Reference Figure 3~Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the pre-treatment part 301 includes a support frame 301a, a sponge wheel 301b, a scraper 301c, a fixing plate 301d and a spring 301e. The support frame 301a is fixedly arranged in the middle part of the top of the base 100, and the support frame 301a is located at the edge of the base 100. The sponge wheel 301b is driven by a motor and rotatably arranged on the inner side of the support frame 301a. The sponge wheel 301b is provided with a pair and clamps the T-shaped guide rail in the middle when the T-shaped guide rail is input.

[0035] The scraper 301c is rotatably set on the side of the support frame 301a, the fixed plate 301d is fixedly set on the top of the base 100, the fixed plate 301d is located on the side of the scraper 301c, the spring 301e is fixedly set between the fixed plate 301d and the scraper 301c, and the end of the scraper 301c away from the support frame 301a abuts against the side of the T-shaped guide rail.

[0036] The sponge wheel 301b is a wheel with a side surface covered with sponge, which can roll on the surface of the T-shaped guide rail along with the motor, and the sponge can remove dust on the surface of the T-shaped guide rail.

[0037] The clamping member 302 includes a pneumatic push rod 302a and a clamping wheel 302b. The pneumatic push rod 302a is fixedly arranged on one side of the enclosure 200 close to the support frame 301a, and the clamping wheel 302b is rotatably arranged at the output end of the pneumatic push rod 302a. The clamping member 302 is provided with two groups, and each group of pneumatic push rods 302a is provided with a pair and symmetrically arranged on both sides of the center of the base 100. The two groups of clamps are symmetrically arranged at different ends of the enclosure 200.

[0038] When placing the T-shaped rail in the device, the pre-treatment member 301 is mainly used to clean the side of the T-shaped rail to prevent dust and impurities on the surface of the T-shaped rail from affecting the search for the inflection point. In the specific operation, the T-shaped rail is first inserted between the two sponge wheels 301b. During the insertion process, the sponge wheels 301b driven by the motor rotate on the surface of the T-shaped rail. In this process, the sponge wheels 301b clean the dust and impurities on the surface of the T-shaped rail. The scraper 301c is continuously in contact with the surface of the T-shaped rail due to the elastic force of the spring 1 301e, further cleaning and blocking the sticky impurities on the surface of the T-shaped rail.

[0039] The clamping member 302 clamps the T-shaped guide rail in order to set a reference for the T-shaped guide rail. After the T-shaped guide rail is completely placed on the top of the base 100, the pneumatic push rod 302a starts and clamps the T-shaped guide rail from both sides of the T-shaped guide rail at the same time, thereby ensuring that the T-shaped guide rail is clamped on the center line of the top of the base 100.

[0040] After the surfaces of the clamping wheel 302b and the T-shaped guide rail are in contact, they can be regarded as line contact, and the thickness of the T-shaped guide rail is almost equal everywhere, so the influence of the bending of the guide rail itself on the position of the clamping wheel 302b can be ignored. Furthermore, when the T-shaped guide rail is placed on the center line of the top of the base 100, the detection of the inflection point of the T-shaped guide rail can eliminate the influence of the tilt of the T-shaped guide rail itself on the straightening assembly 400.

[0041] The remaining structures are the same as those of Example 1. Example 3

[0042] Reference Figure 3~Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the measuring member 401 includes a sliding block 401a, a transmitting plate 401b, a receiving plate 401c and a second spring 401d. A plurality of square holes are provided on the side of the junction between the enclosure 200 and the top of the base 100. The sliding block 401a is provided with a plurality of and is slidably arranged inside each square hole. The transmitting plate 401b is fixedly arranged at the edge of the top of the base 100. A laser transmitter is installed on the surface of the transmitting plate 401b. The receiving plate 401c is fixedly arranged at one end of the sliding block 401a close to the transmitting plate 401b. A laser receiver is arranged on the side of the receiving plate 401c opposite to the transmitting plate 401b. Each transmitting plate 401b is directly opposite to a receiving plate 401c. The second spring 401d is fixedly arranged between the enclosure 200 and the receiving plate 401c.

[0043] Among them, after the laser transmitter of the transmitting plate 401b emits laser, it is received by the receiver on the surface of the receiving plate 401c, so that the distance between the transmitting plate 401b and the receiving plate 401c can be obtained; the measuring parts 401 are arranged in two groups and are symmetrically arranged on one side of each enclosure 200 away from the clamping part 302.

[0044] The rope pulling member 402 includes a sliding hole 402a, a connecting block 402b, a traction rope 402c, a fixed rod 402d, a guide wheel 402e, a winding rod 402f, a gear 1 402g, a driving rod 402h, a gear 2 402i and a driving motor 402j. The number of sliding holes 402a and the number of sliding blocks 401a are arranged correspondingly. The sliding hole 402a is located at the bottom of the sliding block 401a and is opened on the top of the base 100. The connecting block 402b is fixedly arranged at the bottom of the sliding block 401a and is slidably arranged on the inner side of the sliding hole 402a. The traction rope 402c is fixedly arranged on the side of the connecting block 402b. The fixed rod 402d is fixedly arranged on the bottom side of the base 100. The guide wheel 402e is rotatably arranged on the side of the fixed rod 402d. The end of the traction rope 402c away from the connecting block 402b passes around the side of the guide wheel 402e.

[0045] There are two winding rods 402f and they are rotatably arranged at the bottom of the base 100, gear 1 402g is fixedly arranged at both ends of the winding rod 402f, the driving rod 402h is located between the two winding rods 402f and is rotatably arranged at the bottom of the base 100, gear 2 402i is fixedly arranged at both ends of the driving rod 402h, gear 1 402g and gear 2 402i are meshed, the driving motor 402j is fixedly arranged on the side of the base 100 through a bracket, and the output end of the driving motor 402j is fixedly arranged at the end of the driving rod 402h.

[0046] Among them, after the driving motor 402j is started, it drives the driving rod 402h to rotate. After the driving rod 402h rotates, the meshing relationship between gear 1 402g and gear 2 402i is used to drive the two winding rods 402f to rotate. After the winding rod 402f rotates, the traction rope 402c is tightened.

[0047] The correction part 403 includes an electric push rod 1 403a, a movable frame 403b, an electric push rod 2 403c and a concave block 403d. A pair of electric push rods are provided and fixedly arranged on one side of the enclosure 200 close to the clamping member 302. The movable frame 403b is sleeved on the side of the electric push rod. The electric push rod 2 403c is fixedly arranged between the two movable frames 403b. The concave block 403d is sleeved on the side of the electric push rod 2 403c.

[0048] Among them, the electric push rod 1 403a and the electric push rod 2 403c are both composed of a screw driven by a motor. The electric push rod 1 403a controls the movement of the moving frame 403b, and the electric push rod 2 403c controls the movement of the concave block 403d; the concave block 403d is a slider with a notch at the bottom, and the notch covers the outer side of the T-shaped guide rail, which can straighten the T-shaped guide rail.

[0049] The measuring member 401 is used to find the inflection point of the T-shaped guide rail, the pull rope member 402 is used to control the opening and closing of the measuring member 401, and the correcting member 403 is used to straighten the T-shaped guide rail.

[0050] After the T-shaped guide rail is clamped, the staff controls the drive motor 402j to turn on, and the drive motor 402j drives the drive rod 402h to rotate, and the drive rod 402h drives the winding rod 402f to roll out the traction rope 402c. Since the traction rope 402c is lost and the spring 2 401d has elastic force on the sliding block 401a, several sliding blocks 401a begin to slide toward the T-shaped guide rail, and finally all the ends of the sliding blocks 401a are abutted against the bottom sides of the T-shaped guide rail.

[0051] If the T-shaped rail is bent, the sliding distance of the sliding block 401a at the bent part is different, so that the distance between the receiving plate 401c and the transmitting plate 401b is different, so the distance obtained by the laser distance measurement is also different. It is worth noting that the bending of the T-shaped rail is generally not obvious, but the accuracy of the laser distance measurement is also very high, so the gap between different sliding blocks 401a can be displayed. The control device of the device can process the obtained data, and the minimum distance (the convex part of the bend) or the maximum distance (the concave part of the bend) between the receiving plate 401c and the transmitting plate 401b is the inflection point.

[0052] After obtaining the sliding distance of different sliding plates, the control device can control the electric push rod 1 403a to rotate, thereby driving the moving frame 403b to the bending position, and then the electric push rod 2 403c drives the concave block 403d to move to straighten the T-shaped guide rail, and the specific moving direction is from the minimum distance between the receiving plate 401c and the launching plate 401b to the maximum distance between the receiving plate 401c and the launching plate 401b. Straightening the inflection points is performed multiple times until the distance between each receiving plate 401c and the launching plate 401b meets the required accuracy.

[0053] The remaining structure is the same as that of Example 2.
